Through 9/21, Apple is offering a $100 gift card with the purchase of a Mac through the Education Store as a back-to-school special for students, teachers, and educational staff. They are also offering a $50 gift card with the purchase of a new iPad (iPad 2s are excluded), a very rare discount. The card, which is redeemable for apps, music, books, and more from the Mac App Store, the iTunes Store, the iBookstore, and the App Store, is included with your order. Keep in mind that the Education Store already has Macs discounted by up to $200. This is a fantastic deal for anyone with access. Shipping is free and sales tax is charged in most states.
